Brains synchronized by story-tellingIn a 2010 Proceedings of the National Academy of Sciences study, the psychologist Uri Hasson and his Princeton University colleagues had a graduate student tell an unrehearsed story while her brain was being scanned in an fMRI machine. Then they scanned the brains of 11 volunteers listening to a recording of the story. As the researchers analysed the data, they found some striking similarities. Just when the speaker’s brain lit up in the area of the insula – a region that governs empathy and moral sensibilities – the listeners’ insulae lit up, too. Listeners and speakers also showed parallel activation of the temporoparietal junction, which helps us imagine other people’s thoughts and emotions. In certain essential ways, then, stories help our brains map that of the storyteller.
